MisrRerresentation. --Somcbody, who
sigus himself “S. R.,” has been writing to
tho Missouri Republican, from Tahee, Cal, a
long story about the sufferings of newly arrived emigrants in this city.
He says that on the arrival of a
ship at this port the wharves
are usually lined with ‘tau ayerago of eight or nine thousand
miserable looking men, each of
whom rues tho day when he first
listened to tho stories told abont
this land of gold.” Out of this
number, he says at least 5,000
have had no bed the previous
night, aud no “squarc meal”
during the day. This is about
the sum and substanco of this
lugnbrious letter, which, it is
needless to say, is a tissuc of
the most willful misrepresentations and falsehoods, from beginning to end. It is siugular
that our Eastern cotemporaries
are so ready toallow suchanonymous correspondents toso abuse
their confidence, The only reply needed to such a statement, :
js the fact that we havo in this city a free
Labor Exchange, which is widely advertised,
and on application to which any person
who desires can obtain employment, and if
necessary, transportation free to the place
of employment. Hnndreds avail themselves
of this agency fer obtaining work, every
week; and it is usually the ease that
the demand for ordinary labor exceeds the
supply, and at prices which are fairly remunerative,
Since tho above was iu type we have noticed that the Pacific Railroad Company
advertises for 300 hands for laying track—
such as spikers, iron-layers, tie-layers, ete, —
(work whieh any able-bodied person can
perform) at wages varyiug from $45 to $65
per month in gold and board.
Furthermore, we may observe that the
Secretary of the Labor Exchange has made
his mouthly report for June, in which he
says it is searcely possible to over estimate
the demand for female labor on this eoast.
Ineffectual offers have been made as high as
$30 per month in gold, for persons to do
plain cooking, washing and ironing; and
this wheu the same class of labor can be
had in New York for from $8 to $12 incur-.
rency. We may also add the fact that there
is nota man in the almshouse of this city,
(nor need there be) able to perform any
kind of labor. These facts afford an ample
zofutation of the above misrepreseut.tions,
Improvement in Gumming and Sharpening Saws.
Once of the difliculties, savs tho Scientific
American, experienced by practical sawyers
in the use of their saws, is the trouble of
kecping them in working order. A large
portion—toe large—of their time is expended in filing, gumming, or adjusting
their saws, A handy, cheap, and portable
contrivauco for this purpose is certainly a
desideratum. The one shown in tho eneravings contains all these requisites. It
may bo temporarily affixed to auy bench,
moved from one place to auothcr, and is
adapted to all sizes and styles of saws. The
saw, whether circular or straight, cau be
presented to the gummiug wheel at any
angle,
SO
its shaft, which is driven by a belt eu the
pulley, D. The gummer is advanced to the
work by the lever, E, on the shaft of which
isacam, I’, working against a stud on the
inner side ef one of the uprights. A spring,
G, returns the gummer te place, when the
lever, E, is withdrawn,
The foot of the saw support is pivoted or
hinged to the base, H, both being held firmly to the bench by a bolt passing through
the slot, This allows the saw to be set at
au augle tothe gummer. The sawiscanted
in the transverse direction by a joint and
bolt, which permits teeth of any anglo of
edge to be adjusted to the gummer, Two
screws, J, hold the bed of the saw in the
position desired. The bed itself is dovetailed, and a eorresponding sliding block
fits the recess, and is held by a set screw.

The operation of the machine may be
readily understood from the foregoing detailed description and the engravings. It
was patented April 2, 1867, by Thomas T.
Markland, Jr. The machines will be furnished on application to Joshua Hendy,
San Francisco; E. D. Eyre & Co., 248 South
Bighth street, Philadelphia, Pa, or W. H.
Miles, 117 John street, New York. Wo understand a sample machine will he shown
at the Pavilion during the Fair of the Meclave:’ Institute in this city, where practical men can see and judge its merits,

The vicinity of this city was visited by a most unusual display
of electricity on Monday last.
About 8 4, , a dark thunder
clond came in from the west,
near the ‘‘ Golden Gate,” passed
to the northward of the city,
aud apparently directly over the
huge proportious of Mount Tamilpais. During its passage,
sharp and loud peals of thunder were heard in rapid suecession, reminding one vividly of a
tempest in the New England
States. Another similar phenomenon occurred a few hours
later. The atmosphere, or rather
the floating masses of vapor in
the atmosphere of this region,
appeared to beunusually charged with vapor during all the
morning; so much so that for
the first time since tho telegraph
hasbeen iu operation, inconnectiou with this
eity, all business was suspended for the period of two hours by the flashes of lightning
which played along the wires during the
storm at midday. Tlectrical flames danced
around the instruments iu the San Francisco
office, and it is said there were frequent reports like pistol discharges. As a matter of
safety the instruments were disconnected,
else they would probably have been melted,
as is ogcasionally the case where lightning
. storms are frequent. Tho brass of these
instrumeuts in other localities has been
. melted into giobes nearly the size of a

The standard which holds the gummer or

journal boxes ou their upper end, are se-~

saws, its lower portion, N, being formed to
fit the same bed as that which the block

is held by the clamps, O, and adjusted to

. County, and Sau José, four telegraph poles
were shattered by the lightning—something
eutirely uuprecedented in this part of the
country. One of the instrnments in the
office at San José was iujured by the lightning so as to render if unserviceable until
repaired, More thunder was heard iu this
city, within two hours, than has been previously heard altogether fon the last ten
years.
